Question about Kohler Toilet - One Piece with Ingenium Flushing System - San Raphael by

1 Answer

Flushing problems I have 2 Kohler toilets in my apartment. They were installed approximately 2 years ago. One, the first one installed has always worked properly. But, the second one, exactly the same model (I don't know the model but it is a one piece long bowl toilet) has never flushed properly. The flushing mechanism has always been loose and difficult to tighten in a way that stays tight. However that is not the real problem. Generally I have to hold the handle down to get it to flush. And when it does flush, often it has to be flushed a secodnd time as the flow of water is so slow the bowl doesn't alwyas clear all the way through.

Tank needs more water and the flapper has to stay open longer by adjusting chain so the flapper goes up higher when you flush the unit. Practice and you will get it right.

You might want to check the flush cylinder, to see if it has water in it. It has to be water free, that way the air in it, lets it go down easier, during fill up.

low water in the bowl is only caused by the float being to high! the gurgles is Usually because of air coming back up through the pipe, check your vent pipe that come out the roof. this will help the draining.

That is a tricky one. Tighten the tabs, twist into place, then tighten a bit more. They are a pain in the a$$, but with patience you will get it done. Good luck

Water in bowl. water level almost below where bowl saris to widen! , Kohler cimmarron - Toilet tank is full, all water flushes out of tank when flushed it's been this way since we installed it

If I understand correctly, your water level inside the bowl is 3 or 4 inches from the top of toilet seat?
Sounds peculiar to have that water level since you would get splashing etc.
That is not sanitary, and would be a code violation.
Look at side profile of tank.
Look at porcelain behind bowl and you can see outline of "s trap."
This is the internal trap that each toilet has built in.
Purpose of trap is to a) set water level inside bowl and b) just like a sink trap, seal pipe from sewer air from entering home.
Photo shows trap on sample toilet, with line showing approximate level of water inside bowl.
Since photo is at an angle, the line appears to go downward instead of level. Again the line is approximation, and photo intended to show where you can look on your toilet.
Your tank should have similar s-trap feature. From the feature on your tank, you can see what level water is intended to be inside bowl.
Some more expensive tanks, outline of s-trap is not apparent.
If the water level is so high that you experience unsanitary conditions, this is a code violation, and toilet should be replaced.
